Rotary-axle.



UNITED STATES PATENT OFFICE.

Specification of Letters Patent,

Patented Sept. 18,1906.

Application filed July 27.1905. Serial No. 271,519.

To a/ZZ whom it may concern,.-

Beit known that I, CLAY FAULKNER, a resident of McMinnville, in thecounty of Warren and State of Tennessee, have invented certain new anduseful Improvements in Rotary Axles; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to improvements in rotary axles, the object of theinvention being to provide an axle having improved construction ofchannel-axle support with improved bearings for the rotary-axlesections; and the invention consists in certain novel features ofconstruction and combinations and arrangements of parts, as will be morefully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in elevation,illustrating my improvements. Fig. 2 is a view in longitudinal section.Fig. 3 is a view in section on the line :c a; of Fig. 2. Fig. 4 is aview in section on the line y y of Fig. 2, and Figs. 5, 6, and 7 areviews of details of construction. Figs. 8 and 9 are views of amodiiication.

1 represents my improved channel-axle support of general inverted-Ushape in crosssection having a closed bottom 2, which may be formed bybending inward the lower sidel edges or may be closed and be formedintegral With theside and top wall of the support. This closedconstruction of support is very desirable, as it not only adds strengthwith less weight, but also excludes all dust and grit from the bearings.

The support 1 is reinforced at its center by two bands 3, through whichbolts 4 are passed, securing center bearings 5 in the support, and theend bearings 6 are secured in the ends of the support by clips 7 andnuts, as shown.

8 represents the two revolving axle-sections, each having bearingsprecisely alike, and the description hereinafter given of the bearingsfor one axle-section will applyA alike to both. The center bearingcomprises two half-sections 4riveted together and each havingsemicircular bearings fitting into a recessed portion of theaxle-section and having an opening to receive the securing-bolt 4and apocket or depression is formed in the top of the bearing to receivelubricant from a duct or. opening Sa, normally closed by a hingedvcover* 16.

The end bearing, or, in other words, the bearing secured in the end ofthe support by clip 7, is of hollow or box formation to receivecotton-waste and lubricant, has a rounded enlargement 9 on its upperface to pivot in a recess in the support to exactly position thebearing, and has a circular flanged end 10 to close the end of thesupport and exclude dirt and grit. The inner end of bearing 6 is cutaway, exposing an open pocket to receive lubricant through an opening 11in support 1, and a perforated partition 12 is provided between thepocket and waste-compartment, permitting the lubricant to feed into thewaste. Alined openings 13 and 14 are provided in the sides of bearing 6and support 1, respectively, normally closed by hinged cover 15, throughwhich the waste can be inserted and removed from the bearing, and ahinged cover 15 on channel-support 1 is adapted to close both openings11 and 14.

The axle-sections 8 are made tapering at their outer ends to permit thenuts 17 to securely clamp the wheels thereon, yet permit the removal ofthe wheel should occasion require.

A modified form of bearing is shown in Figs. 8 and 9, in which a pocket18 is cast integral with the bearing and on the side thereof at itsiianged end, and this pocket enables the operator to readily insert orremove waste from the bearing and supply the same with lubricant. Thesand-b and of the wheel turning about the flanged end of the bearingalso closes the pocket 18.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In an axle structure, the Combination of a tubular channel havingpermanently closed sides, top and bottom and open at its ends,bearing-blocks in said open ends, axle-sections and removablebearing-blocks ,in said channel for the innerends of the axle-sections.

2. In an axle, the combination with an axle-support, of twoaxle-sections, center and end bearings in the support, metalreinforcing-bands near the center of the support, and bolts passedthrough the bands securing the center bearings in place.

3. A center bearing for a revolving axle- IOO section, comprising twomembers to receive the recessed portion of an axle-sectlon, and

a fastening device permanently securing said bearing members together onthe axle-section.

4.V In an axle structure, the combination with a tubular su portpermanently closed exce t at its en s, of removable bearingbloc issecured in the ends of said tubular support, axle-sections mounted insaid bearing-blocks, and havingannular recesses n ear their inner ends,sectional bearing-blocks to receive the recessed portions of theaxle-sections, fastening means permanently unitin 4 the sections of eachsectional bearing, an means for securing said sectional bearings inplace Within the tubular support.

5. In an axle the combination with a hol-` low support and end bearin sclosing the ends of said support, the sai y end bearings each having awaste-receptacle and acom ret at one end of` municating lubricant-pocthe waste-receptacle, of revolving axles mounted in said end bearings,and removable bearings located within the hollow support and engagingand supporting the inner ends of the revolving axles.

6. In an axle the combination with a hollow support or body, endbearings having flange ends closing said support, the said end bearingseach having a waste-receptacle and a communicating lubrioant-pocket, anda cover hinged to the lhollow support and closing inlets to the pocketand receptacle of each end bearing, of revolving axles mounted in eachend bearing and removable bearings located within the hollow support andengaging and supporting the inner ends of the revolving axles.

7. In an axle, the combination with a hollow support lhaving integralsides, top and bottom open at its ends and provided with ing witnesses.

curved recesses on the inner face of its top near its ends the bottom ofthe support outV engaging the inner ends of the axles, andl means fordetachably securing said inner bearings in place.

8. In an axle, the combination with a hollow support and end bearingsthereon, the latter being provided with lubricant-receptacles, of arevolving axle in each end bearing, -an inner bearing for each revolvingaxle the said inner bearingsvbeing made in sections permanently securedtogether and to the axle-sections, each inner bearing having alubricant-holding recess in its upper face, and means for securing saidinner bearings and the revolving axles connected thereto, to saidsupport.

9. In an axle, the combination with a hollow support and end bearingstherein, of revolving axles mounted in the end bearings, inner bearings,each made in half-sections embracing and engaging the inner ends of arevolving axle and permanently secured together, a lubricator-holdingrecess in the top of each inner bearing, and meansy for securing saidinner bearings and their attached axles to the hollow support.

In testimony whereof I have signed this specification in the presence oftwo subscrib- CLAY FAULKNER.
